PvZ hero’s OP bugged card

I am sick and tired of zombies abusing this bugged card. The quarterly Bonus card says “strength of a zombie becomes 4” NOT increase a zombies attack by 4. Then on top of this the zombie does a bonus attack. Currently the card increases attack by 4 and if there is an empty lane it’s game over. This card is OP and has made playing the plant hero’s less fair and less common. I see very few zombie decks that don’t contain this bugged card.
